The widow of TV pitchman Billy Mays said today that a new investigation backs up her claim that cocaine did not contribute to her husband’s death.

Deborah Mays released a statement, obtained by the celebrity Web site TMZ.com, claiming the family commissioned a second autopsy by an independent medical examiner, Dr. William Manion, who concluded that “chronic cocaine use was not demonstrated by the autopsy findings.”

An autopsy conducted after Mays died in June listed cocaine as a “contributing cause” of his death.

“I do not believe cocaine played a significant contributing factor in the death of Mr. Mays as the autopsy specimens and findings are not consistent with the cardiac conditions normally observed in a person chronically using cocaine,” Manion said.
